@edgarblythe,
Back in Venice, there was a forever vacant lot half a block down our street and then north a half a block. There were a few trees on it, maybe I'm remembering a big palm. I wasn't around that day but heard about a muster of crows going after a cat and the cat's owner, a young girl, trying to save the cat. More neighbors came out. I don't remember the denouement now, just that it happened.
Some years later, Frank Gehry bought that lot to build himself and family a new house, but it never happened - that I know of. Don't now know what happened to the lot, he kept it quite a while. At the other end of that street, turning the corner to the east, was where the Lennon family lived in a big old house (Lennon Sisters of Lawrence Welk fame). That was actually a "crummy" neighborhood back when we moved there, which is why we could get a small cottage type house cheap.
I kinda like crows.
